However, in the rise-up elevator installation method, climbing is performed every second to third floors, and therefore the number of climbing operations is large. Therefore, before lifting the sheave unit (5), it is necessary to carry out the guide rail and landing work on the upper floor of the sheave unit (5). However, since this work is usually done with a scaffold, the number of climbing increases. There was a problem that the assembly time and the dismantling work of the scaffolds increased, and the work time increased.
Moreover, since the elevator cannot be used during the climbing work, there is a problem that the elevator rest period becomes long.
Furthermore, after climbing work, it is necessary to perform landing work on the floor where the sheave unit (5) is installed. However, since the landing cannot be used during the work, the above-mentioned prior art with a large number of climbing operations does not have a landing site. There was also a problem that there were many situations where it could not be used.

The temporary clogging floor (1) is provided with a work floor to ensure the safety of work between the upper hoistway (2) and the lower hoistway (3) and rainproof measures in the lower hoistway (3). It has the function of both roof and roof. Further, by providing the suspension piece (16) on the upper surface of the temporary closing floor (1), the structure can be moved relatively freely even if the climbing is performed a plurality of times by a chain block or a crane.

Next, the work process of the second phase construction will be described with reference to FIG. FIG. 1 shows the work process of the second phase construction.
First, in step S1, a temporary closing floor (1) is installed at the lower part of the upper hoistway (2).

  After the installation of the temporary covering floor (1) is completed, in step S2, materials necessary for installation, gondola (23) and the like are carried in, and then in step S3, as shown in FIG. A stage scaffold (20) and a lifting beam (21) are installed on the upper part of 2). Next, in step S4 shown in FIG. 1, a gondola (23) is installed in the upper hoistway (2). As shown in FIG. 3, one end of the plurality of gondola wire ropes (22) is connected to the lifting beam (21), and the gondola wire rope (22) is wound around the drive sheave (not shown) of the gondola (23). The other end is connected to the beam (24).

  As shown in FIG. 1, after the construction of the gondola (23) is completed, in step S5, the cores of the upper hoistway (2) and the lower hoistway (3) are aligned with each other using the gondola (23).

Here, as shown in FIG. 8, the three guide rails (29), (29) and (29) can be connected to the three guide rails (30), (30) and (30) of the lower hoistway (3). However, since the temporary sheave unit (34) is mounted on one lower guide rail (302), the one lower guide rail (302) is one upper layer of the upper hoistway (2). Cannot be connected to the guide rail (301). The one upper guide rail (301) and the lower guide rail (302) are connected in the third phase construction described later.

  Next, in step S7 shown in FIG. 1, landing work is performed for attaching a landing door (25) to each floor of the upper hoistway (2). As shown in FIG. 7, a temporary closing floor (1) is installed near the boundary between the upper hoistway (2) and the lower hoistway (3), so a landing door (in the vicinity of the temporary closing floor (1) ( 25) cannot be installed. The landing door (25) will be installed in the third phase construction to be described later.

  After that, in step S8 shown in FIG. 1, as shown in FIG. 7, the main sheave unit (26) serving as a new sheave unit is installed on the upper layer hoistway (2), and then in step S9 of FIG. Then, the stage scaffold (20) installed on the upper part of the upper hoistway (2) is removed, and electrical work around the landing of the upper hoistway (2) is performed in step S10. Finally, in step S11, the permanent wire rope (33b) is temporarily hung on the permanent sheave unit (26), and the second phase construction is completed. FIG. 7 shows the progress of construction at this time.

  During the second phase construction, the car (31) is moving up and down in the lower level hoistway (3), so it is necessary for construction work, second phase construction and third phase construction (work related to hoistway connection). And can carry personnel.

A description will be given along the work process of the third phase construction along FIG. FIG. 2 shows the work process of the third phase construction. FIG. 8 is an overall configuration diagram showing the third phase construction.
In the third phase construction, the elevator operation is suspended, and the upper layer hoistway (2) and lower layer hoistway (3) installed in the second phase construction are connected, and the upper layer hoistway (2) and lower layer hoistway are connected. It is a construction that enables elevator operation in a single hoistway (4) consisting of a road (3).

  As shown in FIG. 2, first, in step S21, the temporary closing floor (1) installed at the lower part of the upper hoistway (2) in the second stage construction is removed. Next, in step S22, as shown in FIG. 8, a stage scaffold (38) is installed below the temporary sheave unit (34) installed in the lower hoistway (3). Here, the stage scaffold (38) is the same as the stage scaffold (20) used in the second phase construction. It is also possible to use the stage scaffolds (20) and (38) having the same structure as that of the temporary covering floor (1) described above.

  After the installation of the stage scaffold (38) is completed, in step S23, the car (31) and the counterweight (35) are lowered into the pit as shown in FIG. 8, and in step S24 of FIG. 2, the car (31) And the temporary wire rope (33a) connecting the counterweight (35) is removed.

9 to 12 show a process of removing the temporary wire rope (33a).
As shown in FIG. 9, the electric chain block (42) is attached to the lifting beam (21) installed on the upper part of the upper hoistway (2), and the hoist such as a hoist is attached to the temporary sheave unit (34). And a car cradle (39) and a counterweight cradle (28) shown in FIG. 10 are installed in the pit. As shown in FIG. 9, the end of the temporary wire rope (33a) on the cage side is attached to the hitch (40) to which the rope socket is connected, and the counterweight is similarly attached to the hitch (41) to which the rope socket is connected. The end of the temporary wire rope (33a) on the (35) side is attached.

  Next, the car (31) is lowered and the car (31) is placed on the car stand (39). Thereafter, as shown in FIG. 10, the counterweight (35) is lifted by the electric chain block (42) to loosen the temporary wire rope (33a), and the temporary wire rope (33a) on the counterweight (35) side and the hoisting machine ( The temporary wire rope (33a) on the 32) side is bundled by the wire clip (44). Then, remove the rope socket from the hitch (41) on the counterweight (35) side, lower the counterweight (35) with the electric chain block (42), and place the counterweight (35) on the counterweight cradle (28). To do.

  Furthermore, as shown in FIG. 11, the temporary wire rope (33a) is cut at the position of the hoisting machine (32), and the hoisting machine for the temporary wire rope (33a) is cut from the sheaves (364) (364) of the car (31). Take down the side and take up.

  Then, as shown in FIG. 12, the temporary wire rope (33a) on the car (31) side is held by the rope fixing jig (45) provided at the tip of the lifting machine (43) and is suspended by the lifting machine (43). Here, the rope socket is removed from the car-side hitch (40), and the temporary wire rope (33a) on the car-side is lowered to the pit by the lifting machine (43) and wound. Similarly, the temporary wire rope (33a) on the counterweight (35) side is lowered to the pit and wound. In this way, the temporary wire rope (33a) is removed.

  After removing the temporary wire rope (33a), the temporary sheave unit (34) is removed in step S25 of FIG. Next, in step S26, as shown in FIG. 13, landing work such as installation of a landing door (46) that could not be attached in the second stage work is performed.

  Thereafter, in step S27 shown in FIG. 2, as shown in FIG. 13, the rail construction for connecting the upper guide rail (301) and the lower guide rail (302) that could not be connected in the second stage construction. To do.

The rail construction will be described with reference to FIGS.
As shown in FIG. 15, the rail bracket (48) installed on the inner wall of the hoistway (4) is provided with two rail clips (49) (49) and a pin (47). The rail bracket (48) performs centering and supports a guide rail installed at a predetermined position. At this time, the pin (47) is in contact with the guide rail, and the upper guide rail (301) can be fixed by tightening the two rail clips (49) and (49).

  As shown in FIG. 14, the interval between the upper guide rail (301) and the lower guide rail (302) is set to a size L + α slightly longer than the length L of the intermediate guide rail (303) inserted into the interval. For example, α is about 10 mm.

  An intermediate guide rail (303) is inserted between the upper layer guide rail (301) and the lower layer guide rail (302), and the lower end portion of the intermediate guide rail (303) is connected to the upper end portion of the lower layer guide rail (302). Then, as shown in FIG. 16, the upper layer guide rail (301) is lifted by the electric chain block (42) attached to the lifting beam (21), and in this state, the rail clips (49) (49) shown in FIG. Then, the upper layer guide rail (301) is lowered along the pin (47), and the lower end portion of the upper layer guide rail (301) is connected to the upper end portion of the intermediate guide rail (303). Adjust the joints of each guide rail (301) (302) (303) so that they are in a straight line, and tighten the rail clips (49) (49) in this state to fix the upper guide rail (301). To do.

  After the rail work is completed, electrical work is performed in step S28 shown in FIG. Next, in step S29, as shown in FIG. 17, the counterweight (35) is lifted to the upper hoistway (2), and in step S30 shown in FIG. Hang the permanent wire rope (33b) temporarily hung on the sheave (363) of the counterweight (35).

  Next, the process proceeds to step S31, and after removing the gondola (23) and the beam (24) in the upper hoistway (2), in step S32, the car (31) is tested and raised. Next, in step S33 shown in FIG. 2, as shown in FIG. 18, after removing the stage scaffold (38), final adjustment and inspection are performed in step S34, and the third phase construction is completed.

According to the rise-up elevator installation method of the present invention, the car (31) can be raised and lowered in the lower hoistway (3) during the second phase construction, and the elevator is stopped only during the third phase construction period. Therefore, the rest period of the elevator can be shortened. For example, when climbing every 5th floor with a scaffold installed, the elevator generally has to be stopped for 12 days. According to the present invention, when climbing every 8th floor, for example, 5 days. Just stop the elevator.
Moreover, since the second stage construction is a construction method using a gondola (23), the work efficiency is better than the conventional construction method using a scaffold.
Further, as shown in FIG. 18, the car (31) and the counterweight (35) are connected by the main wire rope (33b) via the sheave of the main sheave unit (26) and the hoisting machine (32). As the car (31), the counterweight (35), and the hoisting machine (32), those installed in the first stage construction can be used as they are for the main installation.
Furthermore, as shown in FIG. 19, since the conventional sheave unit (5) is integrated, it is necessary to lift it every climbing, but this is not necessary in the present invention.

In addition, each part structure of this invention is not restricted to the said embodiment, A various deformation | transformation is possible within the technical scope as described in a claim. For example, as shown in FIG. 3, the hoisting machine (32) is installed in the pit of the lower hoistway (3). However, the hoisting machine (32) is not limited to this and is installed in the middle or upper part of the lower hoistway (3). Alternatively, a machine room can be provided on the side of the lower hoistway (3) and installed there.
Also, in the second phase construction, there is a second floor where the landing door (46) is not installed near the temporary fortress floor (1), but depending on the site conditions, the temporary fortress floor (1), beam (24), etc. are installed. It is also possible to change the floor where the landing door (46) is not installed to the first floor by adjusting the position.
Further, as shown in FIG. 2, when removing the rope in step S24, the temporary wire rope (33a) is cut, and the temporary wire rope (33a) is smoothly wound in a short time. Therefore, the temporary wire rope (33a) is disposable. When the temporary wire rope (33a) needs to be reused at other sites, it is not necessary to cut the temporary wire rope (33a), but it takes time to wind up the temporary wire rope (33a). Cause a prolonged pause. Therefore, cutting / non-cutting of the temporary wire rope (33a) can be selected in accordance with the situation at the site.

  In the second phase construction, three of the guide rail (30) of the lower hoistway (3) and the guide rail (29) of the upper hoistway (2) are connected, and one is not connected. However, if the temporary wire rope (33a) between the sheave (362) and the sheave (363) can be twisted, the temporary sheave unit (34) is placed above the guide rail (30) of the lower hoistway (3). Therefore, it is possible to connect all upper and lower guide rails in the second phase construction. As a result, rail construction can be omitted in the third stage construction shown in FIG. In this case, the temporary sheave unit (34) is locked to the intermediate portion of the guide rail (30) of the lower layer hoistway (3), fixed to the wall surface of the lower layer hoistway (3), or the conventional sheave unit shown in FIG. For example, it can be installed on the slab (59) of the building. In order to more stably install the temporary sheave unit (34), the temporary sheave unit (34) can be placed on the plurality of lower guide rails (30).

  Furthermore, the plurality of steps performed in the second phase construction shown in FIG. 1 and the third phase construction shown in FIG. 2 can be somewhat replaced or simultaneously advanced. For example, as shown in FIG. 1, the order of the landing work in step S7 and the sheave unit attachment in step S8 can be reversed, or both steps can proceed simultaneously. Moreover, it is possible to reverse the order of removal of the temporary covering floor in step S21 and the stage scaffold installation in step S22 shown in FIG. 2, or both steps can proceed simultaneously. Furthermore, the electrical work in step S28 can be performed after or simultaneously with either the counterweight lifting in step S29, the rope hanging in step S30, or the gondola removal in step S31. If the stage scaffolding is removed before the trial run, the trial run and the adjustment can be performed simultaneously.

  Furthermore, in this example, the second phase construction and the third phase construction are each performed only once, but in the construction of a high-rise building, the second phase construction and the third phase construction are performed multiple times, respectively. Elevator can be installed.
